Introduction

The National Radio Astronomy Observatory (NRAO) invites scientists to participate in the NRAO Semester 2015A Call for Proposals for the Green Bank Telescope (GBT), Very Large Array (VLA), and Very Long Baseline Array (VLBA), High Sensitivity Array (HSA), and Very Long Baseline Interferometry (VLBI).

The NRAO especially wishes to highlight new opportunities for joint observations with the Hubble Space Telescope and the Swift Gamma-Ray Burst Mission. The NRAO also wishes to point out that, for the first time, the Large Millimeter Telescope is being offered for inclusion in the High Sensitivity Array (HSA) for 3mm Very Long Baseline Interferometry (VLBI).

Proposal Preparation and Assistance

Proposal preparation and submission are via the NRAO Proposal Submission Tool (PST) available at NRAO Interactive Services. Note that PST use requires registration.
